I wonder how we could figure out the number of slides for five minutes now that we know how many slides per minute.
my math might get a little shaky here, so you might want to do this again just to verify (use that professional calculator tool that came with your computer.
1.16 slides per minute x 5 minutes = 5.83 slides
so, another tricky math concept called ’rounding up’ says that since 8 is bigger than 5, we go ahead and move it to the next decimal place
6.0 slides are needed to make a 5 minute presentation, at the same rate that a 70-slide presentation would last an hour.
Another way of figuring this out is this:
60 minutes Ã· 5 minutes = 12 five-minute blocks in every hour
70 slides in an hour Ã· 12 blocks of five minutes = 5.83 slides per 5 minute block
5.83 rounds up to 6.0 slides you’d need.
I hope this math helps, I’m glad I went to college so I could help you with this one.
